FS-MM Trimmer Attachment is rated 3.9 out of 5 by 15.

Rated 2 out of 5 by Marissa from Not for Manicuring Garden Beds, Great for Brushy AreasI bought this because I do landscaping and wanted a trimmer that wouldn't kill my back. I owned a used Stihl trimmer that worked great, but really hurt my arms & back after any extended use. While this trimmer is on wheels & alleviates that, it is nearly impossible to do any edging to clean up edges of garden beds. You can't flip it like a normal trimmer to get a clean cut or move the head at an angle to get at tight spaces. Great for overgrown areas that don't need to be manicured and just need cut, but horrible for sidewalks, garden edges, etc. If there is some tip or hint at how to achieve a clean cut- I would love some help. Otherwise, I will probably be selling this unit. I have been very disappointed with all of the attachments except the tiller.

Rated 5 out of 5 by farmerbaker from Back-SaverI purchased this to trim around my pond. The Stihl KM130 with a poly head can get heavy. This works great! Cut my trimming time in half and saved my back. Buy with confidence. No line feed problems for me.

Rated 3 out of 5 by Aspelund from Great attachment, bad cutting head/lineGot the FS-MM weed whip for the MM-55. The string pulls in tight on the Auto Cut 25-2 head provided and gets stuck and does not feed, I had to open it up and manually fix it 6 times in one hour.. I even un-coiled and re-coiled the string two times with no improvement. I replaced the head with the Polycut 20-3 head that uses blades and it works like a charm.

Rated 4 out of 5 by Steve0726 from best trimming equipment I ever boughtTop of the line attachment Works super I would recommend this system to any one and everyone I know. One little problem that annoys me is the line feed is to sensitive and feed to fast. Then it wraps around the trimmer head which means stopping and untangling it and shorting the trim line. I have many of the attachments and I am very pleased.
